Problems solved by technology

Due to the individual differences of cashmere goats, it takes a long time for cashmere goats to comb cashmere. A group of cashmere goats usually lasts for about a month. At the same time, each cashmere goat has different cashmere removals in different parts, and some parts have better cashmere removal. It is easy to comb out, and some parts are not easy to comb out.

Embodiment 1

[0031] From January 30 to April 25, 2018, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 100 cashmere goats with similar age and growth status were selected, and 50 of them were routinely managed as the control group. Another 50 according to the artificial light increase program in the present invention carry out artificial light to increase the daily light time of cashmere goats, and carry out comparative experiments. Statistics, the statistical results are shown in Table 2 and Table 3.

Embodiment 2

[0046] On the basis of Example 1, from January 15 to April 15, 2019, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 90 cashmere goats with similar ages and growth status were selected and divided into three groups. There are 9 groups, and a comparative experiment is carried out. The experimental orthogonal design and the results are shown in Table 6 and Table 7.

[0051]The orthogonal design of the experiment is shown in Table 6. This experiment compared different lighting start times (January 15, January 30 and February 15), different light intensities (200Lux, 230Lux and 250Lux), and different The effect of light time length (14h, 15h and 16h) on cashmere carding amount, carding strength and carding time, 9 groups of experiments were designed by three-factor three-level orthogonal experiment. Comparin...

Embodiment 3

[0054] On the basis of Example 1 and Example 2, from January 30 to April 6, 2020, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 40 goats with similar age and growth status were selected. The cashmere goats were divided into 4 groups. Artificial lighting was added according to the lighting program. The colors of the LED lights were red, green, blue and white. There were 10 cashmere goats in each group. A comparative experiment was carried out. The experimental design and results are shown in Table 8. Show.

[0055] Table 8 Effects of LED lights of different colors on the cashmere production of cashmere goats

[0056]

[0057] It can be seen from Table 8 that different colors of LED lights have different effects on the cashmere production of cashmere goats. There was no significant difference between the white LED light group (P>0.05). However, there was no significant difference among the groups in carding strength and carding time (...

Abstract

The invention discloses a method for synchronously delinting of cashmere goats. From January 30, after sunset every day, a red or white LED lamp is used for artificial illumination, and the daily illumination time of the cashmere goats is increased. Specifically, from January 30 to February 18, the daily artificial illumination time is increased by 5.5 h; from February 19th to March 13th, the artificial illumination duration is increased by 4.5 h every day; from March 14th to April 4th, the artificial illumination duration is increased by 3.5 h every day; from April 5th to carding, the artificial illumination time is increased by 2.5 h every day; and the illumination intensity at the height of eyes of the cashmere goats is 230 Lux, and each cashmere goat is fed with 100 mg of zinc methionine every day, so that cashmere of each cashmere goat group is synchronously delinted, cashmere of each part of the body of each cashmere goat also reaches the same state, more time and labor are savedduring cashmere carding of herdsmen, and the cashmere carding amount is higher. The carding time and labor cost of the herdsmen are reduced, the cashmere carding amount is increased, and the income of the herdsmen is increased.

Description

technical field [0001] The invention relates to the technical field of animal husbandry production, in particular to a method for promoting cashmere goats to shed cashmere synchronously. Background technique [0002] Cashmere is a thin layer of fine wool that grows on the outer cortex of the cashmere goat and covers the root of the coarse hair of the cashmere goat. In 2018, the number of goats in my country was 135.7469 million, and the output of cashmere was 15437.76 tons. High-quality cashmere accounted for more than 80% of the global total, and it is a high-quality characteristic resource in my country. [0003] From the end of April to the beginning of June every year, herdsmen judge the time to comb the cashmere by checking the shedding of the cashmere around the ears and eye sockets, and comb the cashmere when the roots of the cashmere begin to loosen. Due to the individual differences of cashmere goats, it takes a long time for cashmere goats to comb cashmere. A grou...
